As an HP Graphite Electrodes Manufacturer, share with you. Graphite as electrode: mainly use petroleum coke and needle coke as raw materials, coal tar pitch as binding agent, made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It is an electric arc model in an electric arc furnace The form can release electric energy to control the structure of the furnace charge, heating and melting the conductor, according to its quality management index level, can be divided into a normal user power, high power and high power. Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It releases electric energy in the form of electric arc in an electric arc furnace. The conductors used for heating and melting the charge can be classified into ordinary power, high power and ultra-high power according to their quality indicators.

Graphite Electrodes

Graphite electrodes mainly include four types of ordinary power graphite electrodes, anti-oxidation coating graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes. Graphite block is a kind of artificial graphite, and artificial graphite is made by artificial heating of coke products. Generally, if it is purified to make high-purity or carbon fiber, the added value is high. Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000℃. It is easy to oxidize at high temperatures. Except for vacuum, it can only be used in a neutral or reducing atmosphere. Its thermal expansion coefficient is small, thermal conductivity is large, resistivity is (8~13)×10-6 Ω·m, processability is better than SiC, MoSi2 rod, high temperature resistance, extreme cold and extreme heat resistance, good price cheaper.

The main content of the graphite electrode system includes four types of corporate normal working power graphite electrodes, anti-oxidation active coatings with graphite electrodes, high-power graphite electrodes and high-power graphite electrodes. When using and some special education products, we must ensure that these technical products have a very good environment when they are used, so that good teaching effects can be obtained. If the graphite electrode gets damp, then China cannot continue to work on the use of graphite electrodes. When we use some high-purity graphite, if these products get damp, it will directly affect our use effect.

We cannot use these products directly.

If we want these products to have a good use effect, then we must ensure that these products have good drying properties, so that we can use a good gua
